Heidi & Spencer

TMZ broke the story that Heidi and Spencer called police today after her mom, Darlene, showed up at their house and wouldn't leave.

We just spoke with Heidi, who tells us, "My mom [Darlene Egelhoff] just showed up to the house unannounced ... and after what she did to me on national TV, I have no desire to see her."

Heidi's referring to a recent episode of "The Hills" in which Darlene told Heidi she did not approve of her plastic surgery. On this week's episode, Spencer claimed Darlene "tried to rape [Heidi] emotionally."

Heidi tells us she immediately notified her personal security team when her mom showed up "pounding on the door."

Heidi claims Darlene is currently speaking with police.

Montag continues, "Her showing up is completely out of line and psychotic. I’m getting a restraining order against her."

So far, no arrests have been made.

Heidi Montag's mother is facing a serious real estate problem back home in Colorado -- and no one could be happier than her son-in-law Spencer Pratt.

TMZ has learned a bank in CO is foreclosing on an undeveloped piece of property owned by Heidi's mom --- Darlene Egelhoff -- claiming she owes $187,385.62 on a $189k loan she took out in 2006.

When we reached out to Spencer for comment, he told us, "If that's true ... that is the best news I’ve heard all day long."

Apparently, Spencer still holds a grudge for the way Heidi's mom handled post-surgery Heidi on the season premiere of "The Hills" ... you remember, when she told Heidi she wasn't pretty and made Heidi cry.

Anyway, Spencer wasn't done going off on Darlene, and added, "Anybody who would do what she did to her daughter – my amazing, beautiful, magnificent wife Heidi – on national television ... should be put in a straight jacket."

Pratt and Emilio Masella just acquired trademark rights on the name "Guid-o-Juice" -- for drink products ranging from energy-fueled concoctions to herbal remedies.

We're told Spencilio's first venture is "what's soon to be the most popular Guido energy drink in the world."

Spencer "Running Bear" Pratt just told us: "Changing our names to Running Bear and White Wolf isn't meant to be disrespectful ... we respect [Native American] heritage and have a sincere acknowledgment of their beautiful culture."

Bear says he and Wolf "would like to invite any Native American tribal leaders to meet with us to help us further understand their culture" ... but we're guessing they'll only do it if cameras are rolling.

After the people formally known as Heidi and Spencer announced their new names, TMZ spoke with a rep from the Rosebud Sioux Tribe of South Dakota, who told us, "Continued stereotyping such as this by people ignorant of our traditional ways is very disrespectful and only hurts our efforts to curtail these stereotypes."

The rep claims they're especially upset because "the names they have given themselves are legitimate names in our tribe." And they're not the only ones pissed at the MTV couple ...

So ... goodbye Heidi and Spencer ... hello White Wolf and Running Bear, respectively.

A rep for the couple tell us Spencer decided to give up his previous moniker, King Spencer, because it was "too much of a burden to have to carry the weight of royalty. "

Instead, Running Bear claims, he and Heidi "are getting more in-tune with our spirituality ... and will be known as the name our creator has given us – our true native-AMERICAN names."

The new and allegedly improved model is anatomically correct, moves at right angles and features top of the line silicone parts for an almost lifelike look and feel.

NASA is reportedly working on a microchip that will one day enable a future version to think on its own.

For the record -- Meryl Streep hasn't even worked with Ron yet.

It all went down Monday while Spencer was playing a game of tug-of-war with his little dog. Sources close to the reality couple tell us Spencer put the little rope toy into his mouth ... when suddenly the rope slipped, and Spencer chomped down through his own tongue -- creating a gaping hole in his licker.

We're told Pratt hasn't been able to talk the past few days and sees it "as a sign from God that he needs to continue to keep his mouth shut in 2010."

In case of an emergency, the 23-year-old may be used as a flotation device.

The hills are alive!

So lifelike.

Speidi showed up at Pure in Las Vegas just as Saturday night turned into Sunday morning.

No one turned back into a frog when midnight struck.

Heidi Montag's other half was pulled over by the LAPD last night because his monster truck lacked mud flaps -- which are required on massive rides so mud and debris doesn't get shot back at other vehicles.

During the stop -- in which Spencer invited the cops to go clubbing with him -- the officers nailed Spencer for not having proof of insurance.

Spencer was eventually sent on his way with merely a fix-it ticket, which requires him to get his vehicle up to code by March 15.

The 23-year-old is a pro at downward facing dog.
